Every time I use the shader, it just makes the entire world jet black and i can't see a thing. And it gives me the message "[Shaders] Error: Invalid program deferred" this is happening with the beta V8.

Hey, so i am not a fan of round suns in minecraft and as this is the only shader that my pc could handle and run smoothly, is there a way for me to change it to a square sun instead on the Toaster Edition? (Enhanced Default is too heavy for my PC)

Please use a different link shortener or don't use that all. Both https://ckk.ai/V71High and https://ckk.ai/Mp6Kt require you to install a program just so I can download the shader. That is completely unacceptable.

This looks absolutely stunning after being without shaders for years, and runs surprisingly well on my 7 year old laptop. I do have two things I need help with though.
1: The (V7) Toaster Edition Link does not work. It only redirects me to an ad, so I got V7.1 Lite. EDIT: I now see the mirror link exists.
2: I get this screen tearing void (shown below) which OptiFine's Custom Sky setting has no connection to. It occurs in the current default 1.14 textures as well. I'd appreciate the help, thanks in advance.

Specs: AMD E1-1200 APU 1.40 GHz; 4 GB Ram, 3.6 Usable; 64 bit

EDIT: Solved. The 'Sky' setting was set to 'off' which just made the sky void out like that.
